I have for about 6 months now been experiencing ‘random’ BSODs relating to 0x000000f4.This has gotten so bad that 2 weeks ago I did a full clean install of Win 7 64 ultimate having previously updated all my BIOS, Firmware etc. to latest versions and am running latest drivers and updates for everything else.I have replaced all my RAM and reconfigured the PCIe order of my GPU and Revo to a variety of set ups.I have tried running basics installs with minimum Software, am running completely new A/V software and tried stabilising my BIOS by setting fixed voltages and removing Marvell driver components (neither have worked – I had read these may be issues).Nothing has worked and I am getting so annoyed I might go and buy an iMac

As for the system, main hardware parts as follows (all have latest drivers, bios, firmware etc):

What happens is fairly typical and will always be from a cold standing boot, usually the machine has not been active for about an hour. The PC boots up as normal Windows loads and then anywhere from about 1 – 5 mins the screen starts to freeze up, the mouse moves but programs stop responding. . then graphics go a bit weird, task bar disappears etc and then BSOD.Once I reboot after this its fine . . no problem, but that’s not the point and I feel I have tried everything and am not getting any closer to either a culprit or a solution.I've been watching Event Viewer like a hawk to see what is happening . . as follows is a highlight form the last week and a new Crash dump from an hour ago, there is never any Warning / Error / Critical logged prior to one of these crashes (after boot up). Ironically this time I was actually looking as Event Viewer and waiting for the logs to load, that’s when it crashed . . someone clearly has a sense of humour, but it’s not me anymore !

These are errors seen over the last few days . . . none of which happened before the crash as noted above and no crashes ever seemed to happen in their vicinity, but they could be indicative. .my gut feeling is its something to do with one of the drives but they have all been tested and seem to be working fine.
